COIN-INTRODUCING DEVICE FOR COIN-CONTROLLED VENDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 547,544, dated October8, 1895.

Application filed January 31, 1895- Serial No. 536,794- (No model.)

To all whom it may concern:

Be it known that I, WILLARD H. GILMAN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Coin-Introducing Devices for Coin-ControlledVending-Maghines, of which the following is a specificalOlL Thisinvention has relation to coin-controlled vending-machines, toymoney-banks, and analogous articles or devices contrived to receive acoin through an opening or slot, back again through which it cannot beremoved.

It is the object of my invention to provide a coin-introducing devicefor machines and devices of the kind mentioned which will prevent theintroduction to the chute or other receptacle by mischievous persons ofsubstances liable to clog the passage-way for coins.

It is also the object of the invention to provide such improvements aswill render it certain that nothing but a coin of the right denominationor a thing of substantially the same dimensions can be carried to thechute to pass through the same to act upon and start the operation ofthe delivery mechanism or be otherwise properly disposed of.

To these ends the invention consists of a coin introducing devicecomprising in its construction three stationary plates or theirequivalents, a revoluble disk or part supported by the central plate andprovided with means to receive a coin at a point at which provision ismade therefor in the top plate, the bottom plate being provided with anopening to receive the coin from the revoluble disk when the coin isbrought opposite the same, all as I will now proceed to more fullydescribe and explain.

Reference is to be had to the annexed drawings, and to the lettersmarked thereon, forming a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure 1 is a plan view of my improved coin-introducingdevice. Fig. 2 is a vertical central sectional view showing a chuteconnected with the parts comprising the invention. Fig. 3 is a plan viewof the central plate of the device, showing the revoluble disk inposition. Fig. A is a plan View of the bottom plate.

In the drawings, A designates the top plate. B is the central plate, andO is the bottom plate. These three plates may be of metal or othersuitable material, as they may also be of the same size, and they may beconnected, as shown in Figs. 1 and 2, by any suitable means.

The central disk B is provided centrally with a circular opening, inwhich is fitted a revoluble disk a, itself provided with circularopenings b c on opposite sides of a square opening d. Through thelatteropening passes a square part of acrank shaft or stud e, which extendsalso through openings in the plates A and O, in which it is adapted toturn, it being provided at its outerend or end above the plate A with acrankf, so that by turning the latter the disk a may likewise be turned.

The plate A is recessed at one side thereof, as at g, in such manner asthat when the disk 0. is turned one of the openings 12 or a may be fullyexposed, as is shown in Fig. 1.

The bottom plate O is provided on opposite sides of the crank-shaft holewith oblong slots r openings 77. in the path or line of travel of theopenings 17 0 when the disk Ct is revolved, and at a point intermediateof said oblong openings in said path or line the said bottom plate isprovided with an opening 2', corresponding in size and form to theopenings or c in the disk at. The width of the oblong openings h isslightly less than the diameter of the openings 1) c t.

j designates light springs connected with the lower surface of the topplate A at points over the openings h and t'.

it designates a chute or conduit communieating with the opening '5 inthe bottom plate. the discharge end of which chute may extend to anydesired point or place.

In the use of the invention, supposing it to be employed upon acoin-controlled vendingmachine, the several plates properly arrangedwill be secured to the frame or casing of the machine at a suitablepoint, and, supposing the device is intended to be used to deposit afive-cent or nickel coin into the chute,

the crankfwill be turned so as to fully expose one of the openings 1) orc in the revoluble disk an, opposite the recess g in the plate A, asshown in Fig. 1. The coin is then placed in said opening and the crankis turned, revolving the disk until the coin is brought over the openingt' in the bottom plate, when the springj on the top plate above saidcoin will press the latter through the opening 2', whence it will fallinto the chute and roll or slide along to and be deposited in properplace in the machine. The coin in passing the openings or oblong slots hin the bottom plate will fail to fall therethrough by reason of thediameterof the coin being greater than the width of said openings. Incase a cent or other coin of smaller diameter than a nickel should beput in the openings 1) or c it will in the revolution of the disk fallthrough the openings or slots 71 in its passage thereover and fail to bedeposited in the chute, and the same result would follow the depositingof other substance in said openings b or c.

The openings h are made oblong for the purpose of making sure of thereception of a small coin or unsuitable substance therethrough, since bya quick turning of the disk a a small coin or improper substance mightbe carried thereover before the springj could act thereon. Said openingsmight, however, in most cases subserve their purpose if made round.

By the means described it will be observed that it is made certain thata propercoin only can be deposited in the chute, and so avoid cheatingthe machine, and that the chute and other parts of the device are keptfree from rubbish calculated to obstruct or clog the operative means soas to prevent its use. Furthermore, by the invention it is madeimpossible to take any money out of the machine through thedepositing-slot after it has passed therethrough.

In the use of the invention on a toy savings-bank or the like the chutemay of course be dispensed with, as may also the oblong slots h.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it maybe made or all of the modes of its use,it is declared that what is claimed is l. A coin-introducing device forthe purpose described, embodying in its construction three platesarranged as set forth, the intermediate plate being provided with arevoluble disk having a coin-receiving opening; one of the outer plateshaving a coin-discharging opening with which the opening in therevoluble disk is adapted to be brought into coincident position, andalso false openings in the line of movement of the opening in therevoluble disk, to receive therethrough things other than a correctcoin, or an object of substantially the same dimensions and the otherouter plate being recessed to permit of a coin being placed in theopening of the revoluble disk.

2. A coin-introducing device for the purpose described, embodying in itsconstruction three plates arranged as set forth, the intermediate platebeing provided with a revoluble disk having a coinreceiving opening; oneof the outer plates having a coin-discharging opening with which theopening in the revoluble disk is adapted to be brought into coincidentposition, and the other outer plate being recessed to permit of a coinbeing placed in the opening of the revoluble disk, and a springconnected with the last-mentioned plate at a point over the opening inthe first-mentioned outer plate.

3. A coin-introducing device for the purpose described embodying in itsconstruction three plates A B O, the intermediate plate 13 beingprovided with a revoluble disk having a coinreceiving opening; the outerplate 0 having a coin-discharging opening and one or more supplementalopenings of less width or diameter than the coin-discharging opening;and the plate A being provided with a recess to permit of a coin beingplaced in the opening of the revoluble disk.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 26th day of January, A. D.1895.
